There have been several experimental studies in the last fifteen years, which show that the gradient of tire static curve in the low-slip region depends on road condition. This result has been in a contrast to the traditional tire theory which relates the low-slip gradient of tire static curve to tire parameters only. This paper presents a detailed experimental analysis of low-slip static tire behavior for different road conditions such as dry concrete, dry and wet ice, and dry and wet snow. The emphasis of the paper is on an analysis of various tire/road effects which can influence the low-slip static behavior, and related tire modeling aspects.
